Tensile and Compression Testing Machine

Technograph TGI series


•New Desk-Top testing mashine with high accuracy, high performance, and simple operation.
■ High Accuracy
Accuracy of ±1 % (JIS Class 1) of the indicated value from 1/1 to 1/1000 of load cell capacity, accurac of ±0.5% (JIS Class 0.5) is available as an option.
Cross head speed range of 0.000 5 mm/min to 1 000mm/min (TGI-50kN to TGI-250kN : 0.000 5mm/min to 500mm/min).
Accuracy of cross head speed is ±0.1 % of speed setting over entire speed range.
■ High performance with simple operatin.
Automatic load cell span adjustment, One-push auto zero, Auto return to test start position (No overshooting), Test condition registration, Manual 3 level speed setting (freely settable), Analog output of test force and position, and support for continuous repeated tensile and compression testing.
■ Increased accuracy, with servo motor resolution four times greater than previous models. Position control is greatly improved, allowing steady operation in low speed ranges.
■ Increased return speed
The return speed can be set as desired between 0.1 mm/min and 1500 mm/min (up to 10kN) and between 0.1 mm/min and 750mm/min (for 50kN and over).


Specification name Specification contents
Maximum test force 250 kN, 100 kN, 50 kN, 10 kN, 5 kN, 1 kN, 500 N, 200 N
Test space Tensile and Compression testing beneath the movable crosshead.
(An optional model is available allowing tensile testing above the movable crosshead.)
Loading method Constant-speed strain loading with high-accuracy AC servo motor and backlash-free precision ball screw
Crosshead speed/permissible test force Within the max. test force over the entire speed ranges.
Test force range Choice of ×1 (AUTO) and ×100 if load cell rated output is 3 mV/V; ×1 (AUTO) if load cell rated capacity is 20 N or less.
When ×1 (AUTO) is set: test force increase/decrease, full scale display, and automatic switching of decimal point position and display units
Test force measuring accuracy ±1% of indicated value in range 1/1 to 1/500 of load cell capacity for both tensile and compression (A high-accuracy model with ±0.5% of indicated value is available as an option.)
Applicable standard JIS B 7721 Class 1 or Class 0.5 and ISO7500-1 Class 1 or Class 0.5
Crosshead speed accuracy ±0.5% of speed setting or ±0.0025 mm/min, whichever is larger
Speed setting method Manual: Numeric input via control panel (0.1, 0.5, 1 to 500 set in 1 mm/min increments)
When using data processing software: Automatically set in accordance with test conditions created.
Manual speed 3 speeds (HIGH/MIDDLE/LOW); each speed freely settable

Notes Note 1: The test force measurement range varies depending on the rated capacity of the load cell used.
Note 2: Testing machines are available with large effective width for models with maximum test force of 50 kN, 100 kN or 250 kN.
Note 3: Models are available with extended stroke.
Note 4: Tensile testing stroke is for maximum test force capacity load cell with the (optional) chuck mounted.
